Gangue brick furnace residual heat utilization system

The invention discloses an attal brickkiln surplus heat using system, which comprises a fume heat interchanger. The smoke inlet nozzle of the fume heat interchanger is communicated with the cooling sect of the attal brickkiln through a pipeline, and a smoke vent is communicated with a discharge flue of the attal brickkiln through a pipeline. A water circulation pipeline of the fume heat interchanger is divided into two shunt-wound spur tracks, with one spur track being a heating spur track and combing back to a fume radiator from the outlet flowing though a heating radiator, and the other spur track being a bath spur track and combing back to the fume radiator from the outlet flowing though a second-class interchanger. One end of the second-class interchanger is communicated with a water source, and the other end is communicated with a bathroom. The invention fully make full use of the fume heat of the cooling sect to heat up warming water and bath water, thus saving the former big sum of money and devotion to building up a boiler, reducing the exhaust emission, increasing the cooling speed of the cooling sect of the attal brickkiln, and greatly improving the producing efficiency.
